Question

X-1/2 + x-3/3 =6
??????

Answer 1

(x-1)/2 + (x-3)/3 = 6/1
mmc (2 e 3) = 6

6:2.(x-1) + 6:3.(x-3) = 6:1.6
3(x-1) + 2(x-3) = 36
3x-3+2x-6 = 36
3x+2x = 36+3+6
5x = 45
x = 45/5
x = 9

Answer 2

x - 1          x - 3
-------   +  ------- = 6
    2             3

m.m.c = 6
3(x - 1 ) /6+ 2(x - 3 )/6 = 36/6 eliminar o denominador
3 x - 3  + 2 x - 6  = 36
3 x + 2 x - 3  - 6 = 36
5 x - 9  = 36
5 x = 36 + 9
5 x = 45
x = 45/5
x = 9
